LOUIE J. HARRIS, OF NEW YORK, N. Y.

FRICTION-CLUTCH.

SPECIFICATION forming part of Letters Patent N0u 710,685, dated October 7, 1902.

Application filed February 6,1902. Serial No. 92,881. (No model.)

To all whom do may concern:

Be it known that I, LOUIE J. HARRIS, a citizen of the United States of America, and a resident of New York, in the county and State of New York, have invented a certain new and useful Friction-Clutch, of which the following is a specification.

My invention relates to a movable couplingor locking and unlocking contrivance used for transmitting motion or for disconnecting parts of machinery; and it has for its object the provision of an apparatus of the kind set forth simple in construction, inexpensive to manufacture, and which operates smoothly and efficiently in practical use.

In order to enable my invention to be fully understood, I will proceed to explain the same by reference to the drawings which accompany and form a part of this specification, in which Figures 1 and 8 represent vertical sections of clutches constructed according to my invention. Figs. 2, 3, 4:, and '5 are elevations of the parts of my clutch, taken on the lines 2 3, at 4, and 5 5, Fig. 1. Figs. 6 and 7 are respectively views in detail of my friction plate or disk and ring shown in Figs. 2 and 3. Figs. 9 and 10 are elevations taken on the line 9 10, Fig. 8; and Figs. 11 and 12 are respectively views in detail of my friction plate or disk and ring shown in Figs. 9 and 10.

Like letters of reference indicate like parts in all the views.

I have found it desirable to make a device for conveying motion from one line of shafting to another by the gradual frictional contact of relatively movable and yielding friction-disks and conical bearing-faces differentially engaged, whereby undue wear and consequent slipping of the parts is obviated, and I have therefore constructed according to my invention an apparatus of the class de scribed embodying the preferred construc tion of parts and their mutual relationship, combination, arrangement, and organization in a composite body or structure, as hereinafter described.

Referring particularly to the drawings, A and A denote two horizontal shafts placed in alinement and normally disengaged from each other, the shaft A being the primary or power shaft, connected with the source of power, as a motor or engine, and the shaft A being the secondary shaft.

Suitably mounted upon and secured to the shaft A, as by the pin a and nuts a and a is one member B of my vertically-located clutch, the same being ordinarily made of metal and preferably constructed sufficiently heavy to serve asa fly or balance wheel.

The inner face of the memberB is provided with two concentric recesses B 13*, each respectively provided with beveled bearing or friction faces Z) and b and also with another concentric interior and preferablydeeper recess B A ring D is situated in the recess 13 and is provided with annular lugs or extensions d, constructed and arranged to engage the vertical grooves b located in the outer wall of the recess B The ring D is constructed and arranged to be moved toward and away from the rear portion of the member B and is held away from the same by the spring 0, the distance being regulated by adj listing-nuts d, located on the bolts (:1 passing through the Wall of the said member B of my clutch and attached to the ring D. Placed on the ring D is my friction plate or disk E, provided with a concen-' tric orifice c. The other member F of my clutch is movable on a shaft A and works on a feather or key a and is engaged with the other member B by means of the resilience of a spring 0 located between the collar F rigidly secured to the member F, and a bearing A attached to the shaft A. I also provide means to disengage the two members l3 and F of my clutch-namely, a lever G, pivoted at g and connected by a link g with the treadlelever G, the end of said lever G being bifurcated to engage and operate the collar F of the member F. The said member F is provided with a beveled or conical face f and also with two concentric recesses F and F Upon the central portion of the inner face of the member F, 1 place a friction plate or disk J, provided with an orifice j. WVithin the recess F, l locate a ring H, movable toward and away from the rear portion of the "member F and provided with a beveled or conical face and having longitudinal grooves 7L, constructed and arranged to register with splinesf, formed on the circular inner wall of the recess F. he said ring H is held TCO away from the wall of the member F by means of a spring 0', and its position in respect thereto may be regulated by means of adj usting-nuts 7L which work on the bolts h, passing through the said wall.

The clutch shown in Figs. 8 to 12 is in all essential particulars like the clutch shown in the other figures, with the exception that the member B in lieu of having a vertical movable friction-plate D is provided with a rigid friction-plate D, secured to the same by screws cl, which plate D and member B are secured to the shaft A by a key a, and the member F instead of having a stationary friction-plate J carries a movable frictionplate J,fastened to blocks K, passing through the face F and secured to and supported by bolts is, passing through the rear portion of the member F and adjusted by nuts k, and between which blocks K and wall are placed springs C In operation a frictional contact is first established by the spring C between the relatively movable and yielding surfaces of the adjacent disks or plates E J at such times when the said plates are not operated by the lever or treadle G. The farther-apart difierential and relatively movable and yielding conical bearing-faces b and b become next engaged,and finally the more distantly located and oppositely-disposed rigid and conical bearing or friction faces f and b are contacted. By means of this gradual and differential engagement of the parts undue wear and also the slipping of the clutch, which has heretofore caused so much annoyance, are entirely obviated.

In order to disengage the members of my clutch, the lever or treadle G is moved in a downward direction, whereby the lever G will be caused tooperate the collar F and thus move the member F of my clutch away from the member B, thereby opening the clutch.

As it is evident that many changes in the construction, form, proportion, and relative arrangement of parts might be resorted to without departing from the spirit and scope of my invention, I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but that such changes and equivalents may be substituted therefor, and that \Vhat I claim as my invention is- 1. In a clutch, a shaft, a friction plate mounted on said shaft, a relatively yielding plate to register with the first-named plate, a spring to normally hold said plates in engagement, and a lever to control the engagement of said plates at will, and also two additional contact-faces, one of the same being yielding as regards the other, said contact-faces being located at an angle to the first-named plates, and controlled by the said lever.

2. In a clutch, a shaft a friction plate mounted on said shaft, a relatively yielding plate to register with the first-named plate, a spring to normally hold said plates in engagement, and two additional contact-faces, one of the same being yielding as regards the other, said contact-faces being located at an angle to the first-named plates, and two oppositely-disposed rigid hearing or friction faces, and a lever to control the engagement of all ofsaid contact-faces at will.

3. A clutch consisting of two members provided with two oppositely-disposed and relatively movable and yielding bearing or friction faces, and also with two additional oppositely-disposed and relatively movable and yielding contact-faces, located at an angle to the first-named faces.
